The level begins with the Marine descending down a shaft on an elevator. Enemies can be seen on the right side of the elevator paths, through windows. The Marine reaches the bottom floor and approaches another elevator. A Civil Security Heavy appears with a Heavy Railgun that the player must eliminate.

After killing the Heavy, the Marine rides two other elevators to get to a platform room with multiple Civil Security Lites. The Marine then activates a teleport into a room swarming with large numbers of Civil Security, firing Rocket Launchers and Plasmaguns. The Marine clears the room and climbs up a staircase and onto a platform. The Player will find a gravitator pushing up a narrow tube. The Player enters the gravitator and is pushed up to the next level.
